Title: Burner control
IPC: F23N1/02
Filed: 1974-05-23
Abstract: 1461653 Burner controls LAND PYROMETERS Ltd 1 May 1975 [23 May 1974] 23134/74 Addition to 1288824 Heading F4T A burner monitor comprises a variator 21, Fig. 2, which is arranged to cause a predetermined fluctuation of the flow of a reactant to a burner 11, a detector 25 for detecting radiation from the flame 24 of the burner and for emitting a signal corresponding to the radiation, a comparator 23 for assessing the polarity of any correlation between the applied fluctuations and the signal from the detector, and an indicator 33 for indicating the assessed polarity. When applied to a boiler installation 10, Fig. 1, having a plurality of burners 11 a single water or aircooled detector 25 movable on a bar 30 serves any selected burner. Burner 11, Fig. 2, is supplied with gas through a pipe 12 controlled by a valve 14 and with air through a pipe 13 controlled by a valve 15, the valves being controlled by pneumatic actuators 16, 17. In operation, signals are supplied by an electric modulation generator 20 to actuator 16 via a transducer 21, and to comparator 23 via a delay circuit 22, thus producing a flickering of flame 24, which latter is detected by an optical assembly 26 and a photo-electric element 27 and a signal is passed through an amplifier 32 to comparator 23. The polarity of the signal is displayed on a centre zero polarity meter 33 and this shows whether a fuel lean or air lean mixture is being supplied. The output from comparator 23 is passed to an integrator circuit 34 which integrates the signal with time, and the output is displayed on a zero quantitive indicator 35, and is also compared in a comparator 36 against a threshold, the pulse controlling a latch providing a hold signal to stop a timer circuit which is reset by a switch 38. This is followed by a digital read-out 39 which indicates the time taken for the integrator to read the threshold. The system provides an open loop, so that the operator can carry out the necessary adjustment; the burner may be monitored at intervals, or there may be continuous monitoring using a trace recorder A2, Fig. 1.

Abstract: 142,382. Hunt, W., (Fraser, W. S.). Sept. 23, 1919. Reciprocating-cylinder pumps.- Relates to lubricating-pumps having one or more cylinders, suspended in the oil reservoir, and reciprocated on their stationary plungers by rotating cams or the like. Figs. 1 and 2 show an arrangement of three pumps B, the cylinders being suspended on rods C on which they are reciprocated by cams K on a shaft rotated by a ratchet-wheel H in a well-known way. The cams rotate in open recesses in the pump bodies so that the latter can be removed independently. The stroke is variable by means of a piece M which is adjusted by a screwed rod N to vary the width of the gap in which the cam rotates. Each cylinder D is reciprocated on a fixed plunger E, and is provided with suction and delivery valves R, S, respectively. The plunger-rod F has a central bore U and is provided with two delivery valves V, W. The space T behind the plunger E when at its maximum is about half the volume of the barrel, and communicates with the bore U through a. radial port. Thus when the barrel moves forward, one half of its contents is discharged through the valves V, W, the other half remaining in the annular space T, and being discharged during the following suction stroke. A pointer P moving over a scale shows the delivery of each unit.

Title: Gain control for spectrophotometers

Filed: 1965-06-03
Abstract: 1,098,228. Spectrophoto-meters. BECKMAN INSTRUMENTS Inc. June 3, 1965 [June 10, 1964], No.23665/65. Heading G1A. In a spectrophoto-meter in order to compensate for the dependency of the detector's output upon the wavelength of the impinging radiation, a photo-resistor is connected to the output side of the detector and is illuminated by light whose intensity varies in accordance with the wavelength of the radiation on the detector; the variation in impedance of the resistor so controlling the gain of the detector as to maintain its output independent of wavelength. The control for selecting the wavelength of the monochromator in the spectrophoto-meter simultaneously adjusts a non-linear potentiometer to appropriately vary the intensity of the light illuminating the photoresistor. The desired characteristic of the non- linear potentiometer is produced by variable parallel connected resistors, which can also be varied to compensate for ageing of the components. In another arrangement the monochromator control adjusts an appropriately shaped aperture to control the intensity of light.
